Police at North Carolina State University were looking for a man who they believe went into two unlocked dorm rooms Sunday morning and stole the occupants' wallets, providing an object lesson for incoming students about security.

Campus officers repeated the advice they give all students for safety, which includes, “Keep your doors and windows locked, even when you are at home.”

They also tell students not to leave valuables in plain sight.

In the first theft Sunday, two students in the college’s Avent Ferry Complex reported that they woke up shortly after 3 a.m. to find a man in their room.

In Syme Hall, police said, two students reported that their wallets were missing when they woke up about 8:30 a.m.

Security video recordings from both places showed a 35- to 40-year-old black man, about 5-foot-10 with muscular build, who was wearing blue jeans, a black T-shirt and a black baseball cap.

At the Avent Ferry complex, the man in the video was seen leaving on foot.

At Syme Hall, police said, he appeared to have driven away in a dark Chevrolet HHR.

Police asked anyone who has any information about the thefts or the suspect to contact them at 919-515-3000.
